RAILWAY-CROSSING.

Specification of Letters Patent.

Application filed September 8, 1913.

Patented Nov. 3, 1914:.

Serial No. 788,682.

The object of my invention is to provide 1 means for preventing the destruction of the casting at the intersection of the two grooves. This object I attain by locating a plug of forged manganese steel or other hard metal 1n an opening in the crossing section.

In the accompanying drawings :Figure 1, is a plan view of a crossing sectionillustrating my invention; Fig. 2, is a longitudinal sectional view drawn to an enlarged scale on the line a-a, Fig. 1; Fig. 8, is a sectional view on the line 6-4), Fig. 1; Fig.

4, is a sectional view on the line 0-0, Fig. 1; Fig. 5, is a perspective view of the plug; and Fig. 6, is a reduced diagram showing the complete crossing illustrating my lnvention.

1 is a section of a crossing. having four arms 2 grooved at 3 for tllGI'BCGPtlOII of the flanges of the wheels passing over the crossing. On one side of each groove is a portion 4 forming a continuation of the rails of the track, and on the other side are the portions 5, forming a continuation of the guard rails.

The crossing sections are made of cast manganese steel and are very hard and cannot readily be machined, owing to the hardness, and while the sections stand considerable wear, the grain of the cast metal is apt to be open and coarse, particularly at the points 6, where the one groove intersects the other, and if there are any imperfections in the casting which would weaken it at this point, the constant hammering of the wheels, as they pass over the grooves, will eventually break particles of the cast metal from the structure and make it defective.

By my invention I recess the crossing section as shown at 7, forming an internal base flange 8, and mount in this recess a plug 9 havin grooves 10 alining with the grooves 3 of t e crossing section, and having a surface on the same plane as the surface of the said section. This plug is made of wrought or forged manganese steel, with the grain densified by the forging process, and the wheels can pass over this plug without causing it to crack or break. The recess 7 is annular, so that the walls can be ground in order to provide a neat fit for the plug, and the plug is circular to fit and has a ground outer surface, so that it will have a driving fit in the crossing section. The plug will be preferably driven until it rests upon the internal flange 8. The plug, however, may be of any shape and fastened into the main body of the crossing in any manner, as by bolts or rivets, and I do not limit my invention to this particular method.

If it is found necessary at any time to re move the plug, the crossing section can be taken up and inverted, and the plug forced out of the section and another plug inserted, if desired.

The plug is preferably cast to conform somewhat to its final shape and then forged into the exact shape desired, after which.

the periphery is ground to fit the recess as above described.

I claim:

1. The combination of a cast crossing section made of hard metal and having a recess at the crossing point, with a forged plug, also of hard metal, located in the recess, both the crossing section and the plug a forged manganese steel plug circular in In testimony whereof, I have signed my shape and having intersecting grooves ahnname to this specification, in the presence of mg wlth the grooves of the orosslng sectWo subscrlblng Witnesses.
